I have a lot of trouble with my hornwort. any time it touches anything it looses its leaves! its so sensitive. I just let it float most of the time, but if I loop it through a cave (so it's not at the surface, and both sides stick out in open water) it looses all leaves touching the object. sometimes it gets itself in situations like that, and cleaning the mess it makes is awful.
does all hornwort do that? is it preventable?
